ANSON BARBER FULLER, OF NEW YORK, N. Y.

IMPROVEMENT IN SWINGS.

Specification forming part of Letters Patent No. 129,940, dated July 30, 1872.

To all whom it may concern:

Be it known that ANSON B. FULLER, of New York, in the county of New York and State of New York, has invented a new and valuable Improvement in Swings; and he does hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part ofthis specification, and to the letters and figures of reference marked thereon.

Figure l of the drawing is a representation of a vertical central section of my invention.

My invention has relation to double swings; and consists in the hereinafter-described construction and novel arrangement of parts, through which motion is given to the swing by the alternate pressure of the feet of the occupants, who are seated facing each other.

Referring to the accompanying drawing, A represents an upright frame of either a sta tionary or portable character. B designates the arms of the double swing, hinged at their upper ends to transverse rods 0 connecting the sides of the frame A. These rods are adjustable to difi'erent positions, so that their distance apart may be varied, holes a for this purpose being made in the sides of the frame. Keys (1. are used to tighten the rods in their sockets. Between each pair of arms B are placed the seats, arranged so thatthe respective occupants may face each other. The seats have backs D, and are placed on a slight backward pitch or incline, so that when swung back the safety of the occupants will not be endangered. At their lower ends the arms B are pivoted to the side-bars E, and are provided with arms F, between each pair of which is journaled a roller, G. The arms F, it will be observed, are at right angles to those wherewith they are connected. H H designate bars journaled to the bars E, and having secured to them the treadle-boards I I, the outer'ends of which rest on the rollers G, in the manner shown. These treadles are used in operating the swing by the feet, and have cleats J J nailed to them to prevent the feet from slipping.

The swing may be operated by the occupant pushing with his feet against the treadle opposite him as he moves forward, or by pressing down on the treadle underneath him as he swings back. In the former case the treadle serves as a lever to elevate the opposite side of the swing from the operator, while in the latter case the operator raises his own side. The former is the better method, as it admits of a freer use of the limbs and a better footpurchase.

The lower ends'of the arms B are adjustable, so that the seats may be set as far apart or as close together as desired. The rollers G serve to very materially lessen the labor of operating.

The treadle and roller may be used with advantage on single swings.

What I claim as my invention, and desire to secure by Letters Patent, is-

The treadles H I H I and rollers .G, applied to double orsingle swings,haviug the pivoted arms F and side bars E, substantially. as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

ANSON BARBER FULLER.
